Mathematics is full of elegant patterns, and one such simple yet powerful concept is squaring a decimal—especially when it comes to values like 1.08. The equation 1.08² = 1.1664 is a fantastic example of how decimal multiplication works when applied consistently. In this article, we’ll explore why 1.08 squared equals 1.1664, break down the math step-by-step, and explain why understanding decimals matters in everyday calculations.


Understanding the Context

What Does 1.08² Mean?

The expression 1.08² means “1.08 multiplied by itself.” Squaring a number is one of the fundamental operations in arithmetic, and when applied to decimals, producing accurate results like 1.1664 confirms our understanding of decimal multiplication.


Math Behind 1.08 × 1.08 = 1.1664

Key Insights

Let’s calculate 1.08 × 1.08 manually using decimal multiplication to understand why the result is 1.1664.

Step-by-Step Multiplication Process:

We treat both numbers as:

   1.08<br/>
×  1.08</p>

Break it down using standard two-column multiplication:

Final Thoughts

  • Times the decimal point’s position:
    Since both numbers have two decimal places, the final answer must have four decimal places.

  • Calculate: 108 × 108 = 11,664

  • Place the result with four decimal places:
    So, 108 × 108 becomes 1.1664

Putting it together:


1.08
× 1.08


864   (108 × 8)

1080 (108 × 10, shifted left one place)
10800 (108 × 100, shifted left two places)


1.1664
```

Sum all shifted partial products:

  • 864
    • 10,800
    • 10800
      = 1.1664

Thus, 1.08² = 1.1664
